view I use a sheet or slip yof aboutthe width of that part ofthe account sheet which-is ruled for the figures of the items, the said sheet or slip being markedrin suoli a manner that the operator, when placing it ony an account sheet or 'ledger leaf, can readily bring apre'- determinedportionof the'proving sheet over or4 cause it to registerwith any desired portion ofthe account sheetA or ledger leaf. The

proving sheet or slip, inits preferred form, hasfonone side ak transfer material, such, .fori example', asusedpon so-called carbon paper,

so that when saidA sheetY or slip is placed.

over the account sheet ori ledger leafand the item to be posted is writtenwith a pencil-or pen on the proving sheet or slip the item isv reproducedthrough theY transfer 'material on tothe account sheet orvledger leaf.` so posting accounts a: facsimile record 1s obtained on the proving sheet -or slipvofl the' items thus posted, and: may then. be compared with the documents from which the itemswere copies, andj errors; if any, can thus be detected.

Thetransfer material mayf'be applied directly to the back face of the proving sheet or checking slip, or carbon paper may be pasted or otherwise fastened to the back of said proving sheet or slip in any suitable manner, with the carbon face, or the face having the transfer material, out. As the continuous handling of the carbon7 side of the proving sheet while posting is liable to soil the operators lingers, and as marks may accidentally be made on the account sheet or ledger leaf by the pressure of the operators hand resting on said proving sheet or slip while writing, I preferably employ a guard to protect the users fingers and the account sheet or ledger leaf. This guard is preferably in the form of a flattened tube made of iiexible material of light weight and through which tube the proving sheet or slip Specification of Letters Patent.

will. run freelyV so that it may be easily adi Justed tov suit: the users convenience;

The proving sheet or checking slip is pref'- erably provided-with' a plurality of spaced openings or Windows through which the' verticali lineson thev account sheet or.' ledger sheet may be seen, andis-also .preferably pro# vided with a heavy line or double lines which, by meansofsaid openings, or windows,v1nay' be brought into register with some corresponding line or lines on the yaccount sheet or ledger leaf, so that the ligure' itenisatof'be" written-on the provingl sheet or checking slipV and to be transferred to the account sheet or ledgery leaf may be brought' intovproper or desired positions on the accounti sheet or ledger leaf. The` proving sheet orsslip may also have lighter vertical"y lines andhoriz'ontal lines for'convenience in causing said: sheet or slipfto properly register with,E corresponding lines on the 4account' sheet or ledgeri leaf, but these lighter linesv are'not' posi-tively necessary andmay be oinittedl ifdesired. The openings ork win'- dows referred; to may besimply cut outy places in theprovingsheet orv slip, or they may be places made transparent asin"win dow envelops. i

In the accompanying drawing Figure l is alface view ofthe improved proving-sheet orxchecking-fslip; andFig. 2 is an edge view thereof; Fig. gris impartial face viewof the` same withVl a; preferred form of guardk applied thereto. v 1g- 4,011 Fig. 3, andlig. is a View similar to Fig:v 4L' illustrating.' a: slightly modified` form of cfuard.

Referrin'gfto-the drawing, 12 denotesthe'l improved proving sheet or checking slip having spaced transverse openings or windows 13. These transverse openings or windows 13 extend laterally across a considerable portion of the sheet 12, so that the vertical lines of the account sheet or ledger leaf may be readily seen through said openings or windows. The front face of said sheet or slip has a prominent vertical line or double lines 14 and is preferably ruled with a series of lighter vertical lines 15 and horizontal lines 16, these lines being formed von the front face a of said sheet or slip. The back face b of the proving sheet or slip 12 is provided with a suitable transfer material which, as heretofore stated, may 'be applied directly to the said sheet or slip, or may be on a separate sheet or slip pasted or otherwise at- Fig. l is a section on line tached to the sheet or slip 12.

To prevent the fingers of the user and the account sheet or ledger leaf from being soiled by the pressure of the hand in holding the proving sheet or slip against the account sheet or ledger leaf a guard consisting preferably of a tube of thin iexible material, as rather heavy paper or rubber cloth, and through which guard the proving sheet or slip may readily run, is preferably employed. In using the improved proving sheet or slip said sheet or slip and the guard are grasped by the thumb and lingers of the user to hold the said sheet or slip against the account sheet or ledger leaf, and the said guard thus prevents the fingers of the user from being soiled by the transfer material used in connection with the proving sheet or slip, and also prevents the account sheet or ledger leaf from being soiled by the pressure of the steadying fingers of the writer, as these lingers will rest on the guard in the writing operation, and not directly on the proving sheet or slip. The guard is loosely mounted with reference to the proving sheet or slip so that it may be moved lengthwise of the latter as the writing progresses. This guard7 in its preferred form, consists of a flattened tube 17, as shown in Figs. 3 and 4, loosely receiving the check slip 12, or it may consist merely of a folded piece of paper or other flexible fabric 17a, as shown in F ig. 5.

In the use of the invention the proving sheet or slip is placed on the account sheet or ledger leaf and is brought into proper register, by means of the openings or windows 13, and by one edge, or by the vertical line or lines on its face, with the proper spaces on the account sheet or ledger leaf,

and the figure items are then written with a pencil or pen on the proving sheet or slip, and of course are also written in facsimile on the account sheet or ledger leaf. When the posting has been completed the proving sheet or slip may be filed away for future reference and affords a checking duplicate of the figure items which have been entered on the account sheet or ledger leaf.

Having thus described my invention I claim and desire to secure by Letters P-atent:

1. A proving sheet or slip having a plurality of spaced transverse windows and having also a surface of transfer material on its back, said sheet or slip being provided with suitable indicating means whereby it may be conveniently brought into register with certain lines or spaces on an account sheet or ledger leaf visible through said windows.

:2. A proving sheet or slip having a plurality of spaced transverse windows and having also a surface of transfer material on its back, said sheet or slip having on itsI face suitable lines whereby it may e conveniently brought into register with certain lines or spaces on an account sheet or ledger leaf visible through said windows.

A proving sheet or slip having a plurality of spaced transverse windows and having also a surface of transfer material on its back, combined with a exible guard loosely mounted with reference to said sheet or slip so that said guard may be moved lengthwise of said sheet or slip. f

4. A proving sheet or slip having a plurality of spaced transverse windows and having a surface of transfer material on its back, combined with a eXible guard consisting of a flattened tube through which said sheet or slip may run freely.

In testimony whereof I affix my signature.
